1. خاصية المنتج
Dichloromethane is a clear, colorless, volatile liquid with a mild, sweet, ether-like odor. It is non-flammable under normal conditions and has excellent solubility in most organic solvents. It is slightly soluble in water and has a boiling point of approximately 39.8°C. Due to its high volatility and strong solvent power

3. نطاق التطبيق والاستخدام
Dichloromethane is primarily used as a solvent in paint strippers, degreasing agents, and aerosol products. It is also employed in the production of polycarbonate resins, polyurethane foams, and as a cleaning agent in electronics and metal industries. In the food and pharmaceutical sectors, it serves as an extraction solvent for caffeine, spices, and hops. Its low boiling point and high volatility make it ideal for use in processes requiring rapid evaporation and minimal residue
4. العبوة والتخزين
Dichloromethane is typically packaged in 200-liter iron drums with a net weight of 250 kg per drum. It should be stored in a منطقة باردة وجافة وجيدة التهوية, away from direct sunlight, heat sources, and incompatible materials such as strong oxidizers, acids, and active metals. Containers must be tightly sealed to prevent evaporation and contamination. During transportation, avoid exposure to high temperatures and open flames. Handle with care to prevent leakage and ensure compliance with local regulations for hazardous chemicals
